Large Images Now Obtained by Crater Tubes

THE neon crater tube has practically revolutionized the television industry over night and has lifted the art from the “peep-hole” stage into the realm of real home entertainment. True, we do not have all the elaborate detail in the images received, that we might like to have, but the crater tube has gone far to brighten up and enlarge the television image. Anyone who has seen the Jenkins television demonstrations—such as those at the New York Radio show will agree, we believe, that the neon crater tube is indeed the device we have long awaited. It requires, however, a special lens-disc, and more energy than the flat-plate lamps which it succeeds.
